The Seco de Palos is a seamount with a summit metres below sea level and is located on the edge of a platform that plunges down to depths of up to 3, metres. As reported by the organization Oceana, the new species is a single-celled organism giant, between 4 and 5 centimeters height, belonging to the group of foraminifera and that mimics the way of capturing the food and the appearance of the carnivorous sponges.

Look forward carnlvoras on gigantic glass sponges! The foraminifer found belongs to a little-known family of these small organisms, schizaminids, of which only 11 species are known.

Web page addresses and e-mail addresses turn into links automatically. Foraminifera are bodies constituted by a single cell, just a few millimeters, similar to the amoebas, and capable of forming a shell or testa, within which they take refuge.

Oceana obtained the images from an undersea robot onboard the Ranger research catamaran. One of the collected stalks D had a calcareous foraminifer f attached and also some flocculated debris d. Thursday, May 25, This technique differs from most deep-sea sponges, which feed on bacteria and other single-celled organisms filtered from carniforas currents.

The stalk in E shows the tightly packed spicules to be slightly twisting with respect to the stalk axis. Ver el perfil de Malcolm Allison H malcolm. Firstly they are silicon based, so they have amazing pure silicon glass esplnjas ranging from the microscopic see picture to ones up to a metre long. Ecology, social and environmental sustainability, emphasis on conservation of rivers and ecosystems, denounces impact of megaprojects. What is striking about the specimens found is that they are 4 cm long, which makes them the largest known specimens of their kind in the Mediterranean.

Pelagic species such as pilot whales, sea turtles, marine birds, swordfish and sunfish concentrate in this area, as well as sandy bottom species such as monkfish and hake. D-F Vistas de tallos.

Malcolm Allison H malcolm. More information about text formats. The species was discovered 30 miles off the southeast coast of Spain, on the Seco de Palos seamount. The Center for Advanced Studies of Blanes CEAB-CSICin collaboration with the environmental organization Oceana, have been discovered, some 30 miles of the coast of murcia, a new species, that is a protozoan giant that mimics a sponge carnivorous.

I feel like it must be the second as that is merely fascinating and incredible while the former is earth shattering to me at least!

These images prove the immense ecological value of this area that was, up to now, unknown. G Detail of the proximal end of a stalk, showing that it is a closed structure, slightly expanded into a bulb-like form. Lines and paragraphs break automatically.

This species has another striking particularity: A General view of the holotype and the paratype from left to right, respectively of Spiculosiphon oceana sp. At espponjas same time as the research on the new foraminifer was taking place in the Spanish Mediterranean, Professor Jean Esponkas, a sponge specialist at the marine station of Endoume, of the Marseilles Centre for Oceanology, stated that he had found a similar organism in undersea caves in the French Mediterranean coast, where carnivorous sponges also live.

The only species of this genus identified until the time was the Spiculosiphon radiata, discovered in Norway, 40 years ago, about meters deep, while its size was half of that found in the Dry Sticks.

These types of sponges have been reported previously to be carnivorous as they tend to get small crustaceans hooked on their Velcro-like spines to be slowly digested in-situ. Submitted by Jonathan on 6 June – 1: Crear un blog gratuito en overblog.

The new species was discovered on a seamount 30 miles off the Spanish coast. Fishermen have been carnvoras with this area since ancient times and have gone there to fish large pelagic species such as the swordfish.

G Detalle del extremo proximal de un tallo, mostrando que es una estructura cerrada, un poco expandida en forma de bulbo. Merrick demonstrates the size of a glass sponge he hopes to find in the next beam trawl.

From left to right: Are we talking all C-C bonds that make known life replaced by Si-Si bonds? Sponges are very cool animals.

Secondly, sponge cells are totipotent, that is, each cell can behave like a stem cell and go on to become any other type of cell that is required. Leave this field blank. Furthermore, thanks to the roughness of its peak that has large rocky blocks and sharp overhangs, trawlers cannot fish on the seamount. That this new foraminifer shares morphological and feeding similarities with carnivorous sponges is probably due carnivorae the fact that both types of organisms live in similar habitats, which have forced them to develop similar feeding strategies.

Notify me when new comments are posted. The investigation carried out by Oceana has verified that a large amount of garbage and abandoned fishing tackle is accumulating on the seamount, both caught on the rocks or lying on the sea floor.

Or a lifeform that uses carbon chemistry for life and uses silicon in its shell? D—F Views of stalks. We know we have discovered a unique ecosystem, but we have also witnessed the effects of human impact”, declared Pastor, a marine biologist.
